ELECTRICAL SWITCH.

Specification of Letters Patent.

Patented Dec. 5, 1916.

Application filed February 2, 1916. Serial No. 75,799.

e it knoivn that I. Huumtn'r A. Ymiiicii, a. citizen of the United StatesT residing at Sunbury, in the countv of .Northumberland and State of. Pennsylvania. have invented certain neiv and useful Improvements in Electrical Switches. of which the follmvingis a specification, reference being had to the accompanying dra-wings.

This invention relates to certain improvements in electrical switches and it is an oh- ]ect of the. invention to provide a device of this general character having novel and improved meansivherehv the same is conveniently and efectivelvcooled and is an improvement on the device disclosed in Patent 7 No'. 1,185,749, uned June 6,1910.

Furthermoreit is an object of my inveni tionto provide a novel andimproved switch ,Whereinthe operatingineans for 'the hlade or blades may bereadil)v applied to or removed from operative assemblage'. 1

The invention also contemplates for an v'object .to provide a novel and improved switchwhereintlie switch blade or blades and the coacting contact lugs or jaws de- [of foreign 'matten which would interfere pend from a frameiemovahly mountedv upon a cooling member'and i nto the chamber of which the same extend.

A still further objectof the invention is' with or obstruct the operation-of the switch.

The invention consistsl in the detailsof constructionA andv in the combination and :ar- -rangementpf thev several parts o f my im# proved switch wherebv certain important advantages are attained and the device is` rendered simpler, less expensive and oth' -wise more convenient and advantageous for fuse, all as will be hereinafter more fully set forth.

vThe novel features of the invention hereinafter be .definitely claimed.

In orderzthat my invention may. be the will better understood, I will now-proceed to describe the same with reference to the accompa-nving drawings. wherein- Figure. 1 is.a longitudinal verticalisuecti'onal view taken through an electric switch constructed 'in accordance with an embodiment of mv invention: Fig. Q is a vie 'partly in top plan and partly in section 0" the device as disclosed in Fig-1; Fig. 3 is a transverse vertical sectional'- view taken through the device as herein embodied. and at one side of its longitudinal center; Fig. 4 is a fragmentary diagrammatic 'view-illustrating certain features 'of theinvention as heein embodied: and Fig. 5 is afragmentari' detail view illustrating-one of the bea-i'- ings for the operating shaft as herein disf closed* As disclosed inthe accompanying drawings, l denotes a receptacle of predetermined dimensions and preferably rectangular in plan with its top face open and the'interiorv thereof affording a cooling chamber'ayand as hereinembdied, the side walls and hottom of said container-are provided with the openings 2 of predetermined diameter and which have' disposed aerosstheir inner ends the shields 3. each of said shields having its 'intermediate portion offset and its extremties secured .to tliefadjacent faces of 'the walls or sides of the receptacle. whereby it ivill be perceived lthat the possibility offoreign substances passing Within the chamis substan-.-

ber a through said openings 2 tially eliminated.: Resting upon the free edges vof the side Walls of the containeris the frameF of a configuration similar', to' that -ofAv the. container 1' and provided at its' inner 1ongitndinal margins relative to the container 1, withthe inturnedanges 4'and having its end Walls lvprovided with the outstanding 'lugs 5 provided with the open slots 6 adapted to receive the threaded Shanks 7 pivotally engaged with the end walls of the Vse container'l, said Shanks .7 'having 4coacting therewith the conventional clamping nuts 8 coacting with the lugs fin awell known manner in order to effectively" and convenientl;r clamp the frame F totlie.cctitainer 1, yet at the same time. permtits ready removal when the necessities of practic lmay so require. The inturned anges 4 serve as a support'for the table or plate A9 produced of suitable` non-conductive material and preferably asbestos 'wood and depending froin said table or plate 9 relative to the. 'container 1 are-the frames 11 arranged at' rdium of the conductors .B connected ivith the =bindingfpost disposed through the table As herein embodied, in v or plate 9. and' electrically connected with the-lugs or jaws 12 through the medium of then-.metallic plates 16.I

improved switch `is of=a-threephase type and as the wiring or electrical connections are conventional, it

thought that a detailA description thereof is unnecessary.

.f Each of the binding posts 14 has the pvotally'1nounted switch plate 18 adapted to coactwvithia contact 'jaw or lug 12 at opposite sides of the intermediate binding post. 14 with which the `saine coacts, Vwhereby it will be'perceived thatwhen the blade is substantially: vertical, the switch is neutral and '--thatfwhenitgcoacts with one of the jaws or lugs 121,; themotor will be'caused to run in 30, n ="second1lug 'o1-jaw 12, the motor will be onef-jdire'ction and.when coacting with the 'causedto run in an opposite direction, as is :wellknownk As herein set forth, the free thebar 19 formed of suitable-non-conductire the samefgeneral direction. -tremities ofthebar or rod 19 arezpositioned The opposite exi within-theA longitudinally disposed Aslots 20 for-media theilower extremities ofthe levers 21 fixedg-toajshaft 22`disposed transversely of the-fameF-fat substantially its longitudinali-centerv and 4ata point4 in alinement with theibinding-posts 14 hereinbefore referred 4 -to,'said'shaft '22 being rotatably mounted in the' recesses 23 formed in the' outer longitudinal edges of the 4frame F and also within the -rrclosure-menibe1-lorllid 2G, whiclris adapted .recesses 24T formed in theflanges 25 of the sito close'.thef"o1ite1face of the frame E It is tofbelobservedjthat the longitudinal inary gins ofthe tab-1e or plate 9 and the adjacent portions of 'fthe longitudinally disposed Y- flanges I are cutaway, as indicated at 27, in =orderto affordnof obstruction to the movement=ofthelever`s '21.

-`"1An` endporti'on'of the shaft 22 extends es teriorly" of'- the 'fra-me F and has secured thereto 'the operating lever 28 adapted to be whereby ityvill be' perceived thatztheV reqextending through the 1 y of the frame and closure-member whereby said shaft maybe readily' removed vmoral of the closure member, means for.'

Shanks 30 pivotally engaged with the ends ofithe frame l*`. and with -which coact the vconventional winged nuts 31 to eieotiyely 'clamp the closure member orlid 26 inapplied position, or permit said lid or closure member 26 to be readily removed when the necessities of practice so require.

While I hav hereinbefore described my improved switc i as being air cooled, it Will be understood that b'y sealing the openings 2. in the container 1, said containermaybe properly filled with a supply of oil. As this construction'and arrangement is obvious, it is thought that an illustration thereof is unnecessary.

VVhile I have disclosed my switch'as a three-phase switch, it is to be understood that I do not limit myself to this `particular form, as it will be at once perceixtedtthat my invention may be employed in "cdhection with any switch of a knife or blade-type.

.From vthe .foregoing description, it' is' thought to beobvious that'4 a switch. conv inexpensive nature and is particularly well adapted foi-'use by reason of the convenience and facility with which it may be assembled, andit. will alsobe' obvious that my. invention is susceptible of somechange and modification without material departure from the principles and spirit thereof and V:for this reason I do not wish tov be, understood as limiting myself to the precisearrangement and formation of the several parts herein shownY in carrying outmy inventionA in prac tice. 'y

A switch of the "character cmn-l prising a container with one 'face' open',- a.

--frame detachablyngaged with `the open facevportion of thecontain'erand having. its engaging,end`- and 'the oppositeendv open, a closure lmember for the outer end of' the .f1-'ame detachably engagdfwith the frame said vclosure 'member being provided with inturned fianges directly Vengageable with f the outer end of the frame,snid ang'es'a'nd fra ine being pro-vided with, registering ces'ses,- stationary contacts .carried by #the frame and extending ,Within the container,
